Why Choose the ABB CAL16-11 Side Mount Auxiliary Contact Block?
The ABB CAL16-11A is a genuine ABB two-pole side-mounted auxiliary contact block designed for use with compatible ABB contactors. Identified by ABB order code SK829002-A, it provides 1 normally open (1NO) and 1 normally closed (1NC) instantaneous auxiliary contact for signalling, interlocking and control functions.
The CAL16-11A uses a screw-type connection and is designed for left-side mounting. It is suitable for standard industrial environments and provides a convenient way to expand the auxiliary switching capability of compatible contactors without requiring separate panel-mounted relays for straightforward status and interlocking functions.
With a conventional free-air thermal current of 16 A, rated insulation voltage of 690 V and IP20 protection, the CAL16-11A is engineered for dependable industrial control applications. Its compact dimensions of approximately 68 × 12.5 × 70 mm support space-efficient installation alongside compatible ABB contactors.

Reliable Auxiliary Switching for Industrial Control Systems
Auxiliary contact blocks provide additional low-power switching contacts that operate with the main contactor mechanism. These contacts can be incorporated into control circuits for contactor status indication, electrical interlocking, sequencing and feedback to other control equipment.
The ABB CAL16-11A combines one normally open and one normally closed instantaneous contact in a compact side-mounted assembly. Its screw-terminal construction, industrial electrical ratings and genuine ABB design make it suitable for maintaining or extending compatible contactor-based control systems.
Typical Applications
- Contactor status indication and feedback circuits.
- Electrical interlocking between contactors.
- Industrial motor control panels.
- Machine control and automation systems.
- Control circuit sequencing and signalling.
- Maintenance and refurbishment of compatible ABB controlgear.
